Funny you should ask after I just rode last night through a hail storm on a high speed descent. Yes, the dreaded inside the case condensation appeared; I lost most of my data, plus incurred BC to PC connection problems. But after drying things out, replacing batteries, and cleaning contacts I successfully restored data from my PC and all appears well.

It's a very good computer, but has lots of quirks. When you understand all of these features, you can do amazing things. Using the rise rate/min function, for example, you can quickly compute watts/kilogram on the fly and compare yourself to the pros.

Make no mistake, though, it's a poor man's Garmin and lacks a strong community of followers.

Strong points: light weight, hundredths of a mile/km precision, baro altimetry with slope, heart rate, and cadence, all in one package with replaceable (relatively) long lasting watch batteries.

Weak points: pseudo chrome finish wears off quickly, long, shallow learning curve, and the software graphs lose vertical axis nomenclature when zoomed. Plus, watertight integrity is compromised in hailstorms.

Here's how I mount mine now. You can see that it's dwarfed by the Android phone which replaces some of its functions.


Bottomline, the ROX 9.0 will hold its own as a light weight wireless BC needing neither GPS nor frequent battery recharging to provide/record tons of data. But in two years time, it may well be obsolete.
